MOUNTING FXT'URE OR DEVICE.

Application filed March 2e, iSL

To all whom it may concern.'

Be it known that Enov rn'rrnns'rnonr Miras, a citizen of the United States, residing at 6 Arthur Avenue, Long Branch, county oit Monmouth, State of New Je .'sey, have invented certain new and useful lmprovements in lviounting Fixtures or Devices, of which the following is a specilication.

This invention relates to a device or tixture particularly intended for use in mounting a wheel hub upon and removing the same trom an anti-friction bearing between said hub and an axle, although the invention is not restricted to this particular use thereof and may be utilized. for mounting or removing any annular element upon or trom a second element for supporting the same.

The primary object of the invention is to provide a device or fixture which comprises a supporting member adapted to be attached to the annular element or wheel hub and carrying a pressure member or ring adapted to engage the second element or bearing, between which supporting member and pressure member relative movement is produced in order to draw the annular element or wheel hub upon or from the second. elc ment or bearing.

Another object of the invention is to pro vide a construction in which the siuoporting member and pressure member may be readily removed from the axle or the like after the wheel hub has been. mounted upon the bearing or the like.

Other objects and features orp the invention will be clear from the following detailed description oi the invention.

rlhe improved mounting device or fixture is illustrated in the accompanying drawings, in which Figure l is a longitudinal sectional view of the mounting device showing the same in use in mounting a wheel hub upon an antifriction bearing means;

Figure 2 is an end elevation, partly in section, looking at the device from the right of Figure l; and

Figure 3 is a detail view showing the pressure member or rino'.

X/Vithout any intention to limit the inveu tion to any particular use of the same, the mounting device is shown in Figure l in the mounting of a wheel assembly for railroad coaches or trucks of the kind described Serial NO. 455,265.

and claimed in my copending application No. .Ll-.55,2641- liled March 24th, 1921. This wheel assembly is indicated in dot and dash lines and comprises an axle l, a wheel hub 2 and anti-triction bearing means comprising inner race members 3, outer race members i and anti-friction disc roller members 5 between each inner race member and the corresponding outer race member, The inner race members 3 are secured side by side upon the axle l against a shoulder 6 thereon by means of a nut 7 threaded upon said axle. The wheel hub 2 is provided at opposite ends thereoff.l with circular series of threaded apertures 8 for the attachment of cover members thereto after the same mounted in piace upon the outer race meinbers il. The further details of this wheel assembly do not form any part of the present invention but it' so desired reference may be made to the copending application iu question for a complete disclosure ot this wheel assembly.

The mounting` device or fixture comprises a supporting member 9 which is shown oi hollow cylindrical form so as to surround the outer race members l of the anti-friction bearing, this supporting member adjacent one end thereof being provided with apertures l0 adapted to receive studs ll threaded into the threaded apertures 8 provided at one end ot the wheel hub 2. The supporting member is also provided at this end with apertures or recesses l2 adapted to receive the nuts 18 threaded on the outer ends of the studs ll whereby the supportingl member is firmly attached or secured to the wheel hub. The studs ll and nuts 13 may be the studs and nuts provided in the wheel assembly tor securing the end cover member to the wheel hub or they may be additional studs and nuts as may bc desired.

The supporting member 9 is preferably made in two or any other number ot sections in order to enable it to be readily removed rom the axle after the wheel hub is mounted upon the race members 4, the supporting member shown in the drawings being formed in two parts, the adjacent edges or which are provided with flanges ill through which are passed bolts l5 whereby the sections are properly secured logether.

rlhe supporting member 9 is provided with a suitable number, `tor example three, or" enlarged or thickened portions 16 which are provided withvthreaded apertures 17 'to receive correspondingly threaded members or rods 18. The inner ends of these rods 18 are reduced in diameter at 19 to extend into apertures 2O provided in a pressure mei'uber or ring 21 which is thereby carried by the supporting member through the medium ot' the threaded rods. rThis pressure member or ring is adapted to engage one of the outer race members 4 of the anti-friction bearing `cated at 22, and mounted upon these squared Vportions vare Vtoothed ypinions 28 which are secured `to the screw-threaded members by means `of pins`2/l or in any other suitable way. The three 'pinions 23 all mesh with a central toothed gear`25 which is annular in form vand lis adapted to surround the aXIe 1, whereby whenanyone of the pinions 23 and the corresponding screw-threaded member or rod '18 Vis rotated the other two piurods are simultaneously rotated tothe same extent.` The hubs of the pinions 28 are squared, as indicated at 26 in Figure 2, to receive a wrench or other tool by means of which the pinions may be rotated. p

In order to permit the annular gear 25 lto be readilyy removed from the axle when the hub has been mounted upon the race V1members 4, this gear is preferably formed in two or more sections which are connected 'together to form the complete `gear but are readily separable to permit lremoval of the gear 1from the axle. 'As shown 'in y'the d awings, the gear 'sections are connected together `ley/plates y27y mounted at 'each side ofthe "geai v25 and boltsv 28 extending through thek plates and gear sections. The plates 27 vare 'each formed in two parts, as indicated in VFigure 2, 'to permit the same to be readily positioned 'and removed, the Vjoints between the plate sections being angularlyseparated from'thejoints vbetween the gear sections so that when the plate sections and gear sections are bolted together in the manner indicated a unitary gear element is provided. Byremoving the boltsthe plate and gear sections may be readily separated and removed. In addition to servingto secure the gear sections together the plates 27 also serve 'by engagement with the opposite faces of the Vpinions 28 to prevent movement of the gear 25 relatively to the pinions lengthwise of the axle, whereby the gear is held in proper` position relatively to the pinions to cause simultaneous movement ofthe latter.

ions andtheir screw-threaded members or' It will be understood from -`the description given above that by applying a wrench or other tool to the squared hub 26 of any one of the toothedpinions 23', this pinion may be rotated and through the gear 25 its rotatil the pressure member or ring 21 carriedfby the vrods abuts against the-faee'of the outer 'race member 4 ofthe antiefrictio'n bearing,

unless said Ipressure member is already in Vengagement with'said race member. Vhen the pressurel member 121 engageswith the race member 4 the rotation 'of the' screwthreaded members 18 within 'the threaded apertures 1'? causesfthe supporting member n. 9 to be moved lengthwise of the axis to the right in Vldigure 1 and the -hub 2, which is firmly secured to the supporting member 9 by means of the studs and nuts 11 and 18, will be drawn to the right and will thereby be mounted upon the outer `race members 4 of the anti-friction bearing means. the hub member has been properly mounted on the race members 4L in "the `mai'i'ner described, the nuts 13 are removed from the studs 1'1 so 'as to disconnect'the supporting member from the` hub and by separating the sections of this'supporting'member and the sections of the *gear 25 the mounting device ma-y be readilyremoved from 'theaxle 1.

lt will be understood that the hubmember 2mav be removed Afrom the race members l by connecting ,theI supporting member 9 tothe oppositeside of thehub member l'from that to whieh it is shown connected in 'Figure 1, the pressuremember 21 thereby being positioned for K engagement with the outer Yface of the other raceme'mber e so that when the screw-threadedl members '18 "are rot-ated the hub member will be ldrawn to the left in Figure l1 and thereby 'removed 'from thefra'ce members. l

1t will fbe understood that, if desired, Vthe 'pinions 23 andgear 25 may in somecases be Y dispensed within which Vevent the wrench or other tool will be applied 4directlyftothe squared portion 22v of anyy one of theV three vthreaded members 18. The gear connections are, however, preferred as theyV provide for equal amounts of rotation being' simultaneouslyl applied to all of the' screw-threaded members 18. y' v Y The ends 19 of. the 'screwthrea'dedf meinbers 18 may be somewhat loosely fitted into the apertures 2() ot'the pressure member 21 in order to permit .a `certain looseness of l movement between i these partsV to fenable the.
